Embodiment

[0013] 1. Add 50 kg of No. 150 national standard mechanical oil into the saponification tank, stir and heat the oil in the saponification tank to 80°C, add 26.9 kg of lauryl hydroxystearic acid, continue stirring and continue to heat up to 90°C to make the twelve Hydroxystearic acid is completely dissolved, and the temperature in the saponification kettle continues to rise after the heating is stopped, and lithium hydroxide solution is added in the saponification kettle when the temperature is naturally lowered to 90 ° C. The lithium hydroxide solution is composed of 4.2 kilograms of lithium hydroxide and 13 kilograms of water. prepared;

[0014] 2. Add boric acid solution when the temperature in the saponification kettle rises to 100°C. The boric acid solution is prepared from 1.3 kg of boric acid and 3.9 kg of water. Continue to heat up and dehydrate. When the temperature in the saponification kettle rises to 130°C, add 1.7 kg Sebacic acid, the temperature rises to 210°C and...

Abstract

The invention discloses a lubricating grease for optical instruments, belonging to the technical field of special lubricating greases. The technical scheme is as follows: the lubricating grease for optical instruments is prepared from the following raw materials in percentage by weight: 55-80% of base oil, 13-38% of thickener, 3-5% of additive and 5-10% of tackifier. The invention also particularly discloses a preparation method of the lubricating grease for optical instruments. The lubricating grease for optical instruments is prepared by thickening the special base oil by using lithium soap and adding excellent additives, has excellent oxidation resistance and lubricating properties, and ensures longer service life. The tackifier ensures the lubricating grease to have certain resistance. The lithium soap and plastic have favorable compatibility, thereby ensuring the sealability of the lubricating grease.

Description

technical field [0001] The invention belongs to the technical field of special lubricating grease, in particular to an optical instrument lubricating grease and a preparation method thereof. Background technique [0002] Optical instruments are very delicate instruments that are generally expensive and easily damaged. In order to protect the optical instrument, the sliding or rotating parts of the optical instrument and the frictional parts close to the surface must be lubricated and sealed. Lubrication is to ensure that these moving parts will not be worn for a long time, and sealing is to ensure that impurities cannot enter the interior of the optical instrument. Lubrication is the basic function of grease, and the torque of optical instruments is very small, so the grease of optical instruments must be low torque. The grease used in optical instruments must have good compatibility with the plastic of the instrument. The compatibility of the grease can make the plastic e...
